1. An example of an exponential function is y=8^x. Convert this exponential function to a logarithmicfunction. Plot the graph of both the functions.
2. Graph these two functions
? An exponential function f(x)=6x-2
? A logarithmicfunction f(x)=log9x
3. Look at the graphical representation below and derive

Define the logarithmic integral li(x) as the integral of the function 1/(log t) from t = 2 to t = x, where x > 2 and "log" denotes the natural logarithm.
(a) Determine constants A and B such that li(x) can be expressed in the following two forms:
(i) li(x) = x/(log x) + A + g(x), where g(x) is the integral of the function

Common and Natural Logarithms
1. For the exponential function ex and logarithmicfunction log x, graphically show the effect if x is doubled.
The exponential function f (x) = e^x
you will also need to graph f (x) = e^(2x).
The common logarithmicfunction f (x) = log x
You will also need to graph f (x) = log (2x).

In exercise 53-56, begin by graphing f(x) = log2 x. Then use transformations of this graph to graph the given function. What is the vertical asymptote? Use the graphs to determine each function's domain and range.
56. h(x) = 2 + log2 x
The figure show the graph of f(x) = log x. In exercises 59-64, use transformations o
